    Local and Remote Operation LOCAL AND REMOTE OPERATION When the meter is operated from a host computer it is said to be operated “remotely”. When the meter is operated from its front panel, it is said to be operated “locally”. Some operations, such as setting the communication parameters for the RS-232 interface, can only be performed from the front panel .
